An automated assessment based on available data — not a substitute for an independent inspection or professional legal/financial advice.

Significant ad/registry mismatch: the ad lists '440i' but the official registry shows '4 Series' — ask the dealer to confirm exact model/variant and show registration papers.Extensive engine/transmission tuning and a catless downpipe (seller: custom map, catless downpipe, XHP gearbox optimization, high-pressure fuel pump) — ask for dyno sheets, workshop receipts and whether any factory warranty/recall coverage was voided.High owner count: 9 prior owners recorded — ask why so many ownership changes and for full service history to show continuous maintenance.Price well above market: asking 389,900 SEK vs Blocket median comparable 234,800 SEK and fair range 199,800–274,900 SEK — seller needs to justify a premium for modifications with documentation.Recalls exist for this model (airbag propellant, starter-relay corrosion) but VIN-specific completion not verified — request manufacturer/VIN recall check and service proof.Service intervals by time (brake fluid every 2 years; air/fuel filter and spark plugs every 4 years) suggest items may be overdue on an 2018 car — ask for dates/receipts for these services.Conflicting statements in ad about catalyst (ad mentions 'catless downpipe' but seller parenthesis says 'Catt finns kvar') — verify exhaust configuration and emissions compliance before purchase.Sold by a dealer — konsumentköplagen applies, giving stronger consumer protection than a private sale.Besiktigad (inspection) valid until 31-10-2026.Two keys and 'very good service history' claimed by seller; dealer can provide warranty options (6–36 months) through a named provider.

CautionWorth a closer look
  • Significant aftermarket tuning and catless/downpipe increases risk to drivetrain and emissions systems.
  • High prior-owner count (9) raises the chance of inconsistent maintenance.
  • Mileage is moderate (144,980 km) and consistent across classifieds history; not a rollback risk.

💰 Market valuation

Asking 389,900 SEK — fair range 199,800–274,900 SEK (Overpriced, from 31 comparables).

Valuation is based on a Blocket median of 31 comparable listings (not trim-matched). Median comparable is 234,800 SEK and fair private/dealer range is 199,800–274,900 SEK — the asking price 389,900 SEK is substantially above that range and appears overpriced unless well-documented modifications and service records justify the premium.

📢 Official recalls (EU Safety Gate)

2 of 10 total recall campaigns issued for this model apply to this vehicle's specific model year — not the model's entire recall history.

  • BMW 4 series (2015 – 2021) (2025-11-01) — Water may come into contact with the starter relay and gradually cause corrosion. This could affect the electrical connection inside ...
  • BMW 4 Series (2013 – 2018) (2024-09-15) — The propellant in the driver airbag may deteriorate over time. If the airbags deploy, it could result in fragments from ...

This shows official recall campaigns issued for this model and year — whether THIS specific car has already had the fix applied isn't verified here. Check the chassis/VIN with the manufacturer's own recall lookup tool to confirm.

Estimated annual running costs: road tax 1,416 SEK, fuel (assumes 10,000 km/year) 13,056 SEK, routine maintenance estimate 2,800 SEK. Insurance range is an estimate (6,000–12,000 SEK) and not a quote from a specific insurer.

Indicative only, not a real quote — assumes the full asking price financed with no down payment over 5 years at a typical 5–8% secured car-loan APR. An unsecured personal loan usually runs higher, and your actual rate depends on your own credit assessment.

Recommendation

Negotiate — get full paperwork and a pre-purchase inspection before agreeing on price.

The car is modified (engine map, downpipe, gearbox tune) and the asking price is far above market median; if you still want it, require full dyno/workshop receipts, VIN recall completion proof, and a professional pre-purchase inspection — only then negotiate from the market-based range.

Suggested offer range: 235,000–265,000 SEK

✅ Before you buy

❓ Questions to ask the seller

  • Can you show Transportstyrelsen's "Fordonets skulder" (vehicle debt) service, or otherwise confirm there is no outstanding vehicle tax, congestion charge, or parking-fine debt tied to this vehicle? Unpaid vehicle debt transfers to the new owner in Sweden, not the previous one, and can lead to Kronofogden seizing the car.
  • Please provide dyno printouts and workshop receipts for the ECU remap, catless downpipe (or clarify if the catalyst is still present), XHP gearbox optimization and HPFP upgrade.
  • Can you show stamped service records or invoices for oil, spark plugs, air/fuel filters and brake fluid, with dates/mileages?
  • Why does the ad call the car '440i' while the registry lists '4 Series'? Please provide registration certificate/vehicle papers showing exact model/variant.
  • Has any recall work (airbags, starter-relay, etc.) been completed on this VIN? Please provide manufacturer recall check or service confirmation.
  • Why are there nine prior owners listed in the registry? Any repossessions, lease returns or short-term ownership reasons?
  • Does the dealer warranty cover the engine/transmission after the tuning, and do you offer a test-drive with a focused gearbox/shift inspection?

🔍 Inspection checklist

  • Never pay a deposit or the full price before you've seen and test-driven the car in person — be wary of pressure to decide immediately ("today only" pricing), or a seller who avoids meeting or an independent inspection.
  • Pay by bank transfer or Swish, never cash to someone you haven't met or verified, and complete the registered ownership transfer (ägarbyte) digitally at handover rather than leaving it for later.
  • Verify presence/absence of catalytic converter and inspect downpipe for welding or modifications; request emissions/test result if cat altered.
  • Run the car on a dyno or at least review the dyno printout while the seller explains the remap; verify claimed output and tune vendor.
  • Complete a thorough test drive to check XHP gearbox shift quality and hesitation under load; listen for transmission noise.
  • Check documentation for regular services (oil, spark plugs, filters, brake fluid) and match receipts to service intervals.
  • Inspect BC Racing coilovers, wheels and suspension for wear, leaks, and correct installation.
  • Have a mechanic check for starter-relay corrosion area and whether airbag recall work was done (visual plus VIN check).
  • Confirm VIN on car matches registration and dealer paperwork; verify no hidden liens or unresolved issues.

What this report doesn't cover

  • No accident, insurance, or police-record source is checked — the damage assessment below reflects that gap, not a clean history.
  • No community-sourced known-issues research is available for this model yet — the known-issues section is not populated.
  • Recall campaigns are matched by model and year only — whether this specific chassis has already had the fix applied is not verified.
  • The mileage history below is a real but partial view — car.info has 33 more historical entries for this vehicle that require a logged-in account to see, which this report does not use.
  • Outstanding loan/lien status (belåning) is not part of Sweden's public vehicle records and cannot be verified by this report — ask the seller directly and consider a written confirmation in the sale contract.
  • No insurance/accident/vehicle-damage (claims) database was checked here; damage summary confidence is low.
  • Known model-issue research is not available (knownModelIssues is null), so community-sourced failure modes were not included.
  • Recall listings are model-level; VIN-specific recall completion could not be verified in this report.
